The Indian benchmark indices closed on a positive note on Aug 13, 2025, whereby Sensex was up 0.38% to 80,539.91, while Nifty ended up 0.54% to 24,619.35.
As the Nifty 50 contracts are scheduled to expire on Aug 14, 2025 after a roller coaster week. Traders remained cautious ahead of expiry, reflecting in subdued market sentiment.
Ahead of the Nifty’s weekly expiry on Thursday, Aug 14, 2025, the National Stock Exchange (NSE) has placed one stock under the Futures and Options (F&O) trading ban.
This restriction is enforced when the open interest in the stock crosses 95% of the market-wide position limit (MWPL). While fresh derivative positions are disallowed, the stock continues to be available for trading in the cash market.
The stock under the F&O ban for Aug 14:
Ahead of expiry, PG Electroplast shares closed 5.76% lower at ₹485.55 after opening at ₹522.00 on NSE. During the day, the stock touched its day's low of ₹483.05.
PNB Housing Finance shares ended 0.81% higher at ₹773.40, reaching a day high of ₹775.50
On Aug 14, 2025, RBL Bank’s share price was up by 0.57% to close at ₹254.80, compared to its previous close of ₹253.35. The stock opened at ₹254.35 and touched an intraday high of ₹258.30 and a low of ₹252.20.
A stock is placed under the Futures & Options (F&O) ban when its open interest surpasses 95% of the Market-Wide Position Limit (MWPL), as per NSE guidelines. During this period:
This rule is designed to limit excessive speculation and ensure orderly market operations, particularly during high-activity periods like contract expiries.
Nifty 50 F&O contracts usually expire on Thursdays. If Thursday is a trading holiday, the expiry is moved to the previous trading session. All settlements occur at the normal market closing time.
On trading platforms, weekly expiry contracts may be categorised under the monthly series during expiry week to maintain consistent tracking and classification.
With PG Electroplast and 3 more stocks under the F&O ban on Aug 14, 2025, traders should closely monitor open interest levels and adhere to NSE rules. These regulations play a crucial role in preserving market stability and minimising excessive volatility during the weekly expiry cycle.
